COUPLING FOR PIPING SECTIONS Filed Dec. 14, 1953 INVENTOR. PAUL lS/DOE ACAEEMAN I U i e ew Patent The present invention relates to a bonding device. for

piping constructions in which a retaining angularpart is Tl provided on its adjacent external surfaces with bearings in which the tubes to be held together are secured. This device more particularly is suited to enable at least two tubes to:be coupled together, in such a manner that the latter are located in. transverse directions and in the same plane.

It is an object of the present invention to provide means facilitating the retention of a third pipe in perpendicular direction to a pair of pipes extending in transverse directions in the same plane.

Another object of the invention is to provide a retaining part which has a supporting bearing inside the angle formed by its two adjacent flanges, which enables a third tube, which passes inside the angle formed by the two flanges, to be held in predetermined position relative to two transverse pipes disposed on the outside of said flanges, respectively.

This retaining part is combined with another retaining part or cover whose'supporting bearing is applied so that it fixes on the tube situated in the angle of the angular retaining part.

Another purpose of the invention is to operate so that the transverse tubes, resting in supporting bearings of the external surfaces of the angular retaining part, are fixed by means of clamps which envelop them on the external side and then traverse the flanges of the retaining part, so as to accommodate tightening nuts, this method of fixing having the advantage of being simple and rapid.

Another purpose of the invention relates to a bonding device for tubular constructions which comprise: a retaining part co-operating with a retaining part or cover, for holding a first tube; the retaining part having bearings on its adjacent external surfaces in which other tubes are held by means of clamps or other tightening means, stops being inserted between the retaining part and the supporting part, these stops having the effect of balancing the tightening of the tube.

Other purposes and objects of the present invention may be realized from the description and drawings hereinafter given and shown, in which:

Figure 1 is a perspective view of a construction part Whose tubular sections are secured by a coupling according to the invention.

Figure 2 is a plan view of this coupling.

The coupling shown in these drawings comprises a retaining part 1 whose section has two adjacent flanges 1 and 1 which form an angle of 90 between them.

On these two external surfaces, this retaining part 1 is provided with cylindrical supporting bearings 2 and 3 in the shape of grooves.

In the example shown, these grooves are made along horizontal axes and located in the same horizontal plane.

The groove 2 receives a tube B which it centers and holds along a horizontal axis X, X, whereas the groove 3 receives a tube C which it holds in the same plane along horizontal axis Y--Y'.

The clamps 9 and 10 also ensure the tightening of the tube A between the supporting part 1 and the supporting part 7.

According to one of the particular features of the invention, the retaining part or cover 7 is provided on one of its adjacent flanges with stops or spacers 13 and 14 extending toward the complementary flange of the retaining part 1.

These stops have the purpose of balancing the tightening of the vertical tube A. These stops 13 and 14 arrive from the factory with the retaining part or cover 7. In the absence of the stops 13 and 14, the mounting of the device proves to be very complicated, thus involving a considerable loss of time.

The coupling device described above affords numerous advantages and more particularly the following:

(1) It enables two tubes whose directions are transverse, to be fixed in the same plane in an eflicacious manner and without diminishing their strength.

(2) In a vertical direction, the bond is eifected in an equally efficacious manner, thus preventing slipping owing to the extensive holding surfaces of the bearings 4 and 8.

(3) The stops 13 and 14 fitted on one of the flanges 7 of the cover 7 enable the tightening to be balanced. Owing to this, the vertical tube A is rigidly secured between the parts 1 and 7.

(4) The device is extremely easy to make, and consequently quite cheap.

(5) Fixing by means of clamps 9 and 10 affords the advantage of preserving the exterior from any dangerous and hindering projection.

It is clearly understood that the invention is not restricted to the forms of embodiment precisely described and shown. If required, recourse may be had to other forms of embodiment without going outside the scope of the invention for that purpose.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:
